TLDR
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz tone, and a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation.Abstract:
Level of arousal was manipulated by having subjects perform arithmetic tasks during a habituation procedure, which consisted of 55 presentations or a 1000 Hz 80 dB tone For one group a threat of shock was added to the task performance in order to include aspects of stress in the arousal manipulation These two groups were compared with a group who heard the same stimuli but were simply instructed to relax The three groups differed in level of arousal according to KEG signs of drowsiness, skin conductance level, and frequency of spontaneous skin conductance responses, All three groups differed from each other in number of trials to habituation criterion for skin conductance responses to stimuli Since the delay of habituation was seen tin- both the Task group and the Shock-threat group, it was concluded that the effect was not bound to aspects of stress but was a general effect of increased arousal For vasomotor responses an analysis in terms of habituation was difficult to apply because the two high arousal groups were very unresponsive from the beginningread more

The Affective Significance of Skin Conductance Activity During a Difficult Problem-solving Task
TL;DR: The meaning of spontaneous skin conductance activity, and its relevance to appraisal theory, is examined in this paper, where the authors hypothesize that spontaneous skin activity is correlated with appraisals of problem-focused coping potential.

Physically Abused Children's Regulation of Attention in Response to Hostility
TL;DR: Data suggest that the emergence of anger leads to increases in anticipatory monitoring of the environment among children with histories of abuse and risk factors in the development of psychopathology are discussed.

Use of skin conductance changes during mental stress testing as an index of autonomic arousal in cardiovascular research
Sue C. Jacobs,Richard Friedman,Richard Friedman,Richard Friedman,John D. Parker,Geoffrey H. Tofler,Geoffrey H. Tofler,Alfredo H. Jimenez,James E. Muller,James E. Muller,Herbert Benson,Herbert Benson,Peter Stone,Peter Stone +13 more
TL;DR: Skin conductance level can serve as a stable and useful index of autonomic arousal in clinical trials, even in patients using beta-blocking medications, and nadolol had no significant effect on skin conductance.

Aging, selective attention, and inhibitory processes: a psychophysiological approach.
Joan M. McDowd,Diane L. Filion +1 more
TL;DR: The authors investigated the efficiency with which younger and older adults allocate attention to relevant and irrelevant stimuli, and found that older adults exhibited nondifferential orienting across the two instruction conditions, suggesting an age-related deficit in the ability to inhibit attention to irrelevant stimuli.

Power Spectral Density Analysis of Electrodermal Activity for Sympathetic Function Assessment.

TL;DR: In this article, a novel frequency-domain approach to quantify sympathetic function using the power spectral density (PSD) of EDA was proposed, which was used to examine if some of the induced stimuli invoke the sympathetic nervous system's dynamics which can be discernible as a large spectral peak, conjectured to be present in the low frequency band.

A physiological model of phobic anxiety and desensitization.
Malcolm Lader,A.M. Mathews +1 more
TL;DR: An alternative explanation consistent with the above postulate states that the underlying mechanism of systematic desensitization is identical with that of habituation proceeding under optimal conditions (the “maximal habituation” hypothesis).

The orienting reflex during waking and sleeping
Laverne C. Johnson,A. Lubin +1 more
TL;DR: There was little, if any, habituation of the OR during sleep, and the presence of a stimulus-evoked K complex was associated with increased responsiveness in all autonomic variables, but presence of eye movement bursts wasassociated with decreased cardiovascular response to the tone.

Self-reported arousal: further development of a multi-factorial inventory.
Anders Kjellberg,Gunilla Bohlin +1 more
TL;DR: The previously presented inventory of self-reported arousal, which contained four factor analytically derived scales, was further developed in the following way: the original factor pattern was cross-validated and a new response scale was constructed which proved to be superior to the old one.
